Abstract

A novel Gram-stain-negative, aerobic, yellow-pigmented bacterium was isolated from seawater of Aoshan Bay, and designated as strain ASW18. Strain ASW18 was a long-rod-shaped bacterium without flagellum and lacked gliding ability. Based on 16S rRNA gene phylogeny, strain ASW18 showed the closest relationship to MCCC 1A06690, with a sequence similarity of 97.0 %. Strain ASW18 was able to grow at 25–40 °C, at pH 5.5–9.5 and with 0.5–9 % (w/v) NaCl. The genomic DNA G+C content of strain ASW18 was 37.3 %. The predominant cellular fatty acids of strain ASW18 were iso-C, iso-C 3-OH and iso-C G. The major polar lipids were phosphatidylethanolamine, phosphatidyldimethylethanolamine, an aminolipid and three unidentified lipids. The respiratory quinone of strain ASW18 was menaquinone with six isoprene units (MK-6). Based on the present polyphasic analysis, strain ASW18 represents a novel species of the genus , for which the name sp. nov. is proposed; the type strain is ASW18 (=MCCC 1K04203=KCTC 72852). In addition, it is also proposed that should be reclassified as comb. nov.; the type strain is CSW06 (=CGMCC 1.15761=JCM 31455=KCTC 52375=MCCC 1K03195).
